"She was covered in mud, lying motionless in a ditch when passersby first noticed her," Patricia Blackwood, operations officer for Guardians of Rescue, tells The Dodo. "It was as though she had given up hope and was waiting to die."

"Now what you have is animals come out of hiding," Robert Misseri, founder of Guardians of Rescue, tells The Dodo. "Animals wandering lost, hurt, starving. This is what you're dealing with on an everyday basis."

"You come up to a house, there's no one there. No one around," he says. "You can see dogs haven't eaten. No water, no food, nothing. Just chained up."

But alive.

Last week, rescuers were tipped off to three dogs trapped in a yard. Their owner had fled, leaving them with empty bowls and no means of escape.

But thanks to a neighbor who gave them food and water, they managed to survive until help got there.

"After assessing the situation, the owner was located and ownership was signed over and we quickly moved in to remove them from where they had endured rising waters, hunger and thirst," Blackwood says.

Where rescuers once faced a flood, they now find themselves bogged down by a severe shortage of resources.

"Until [the animals are] medically cleared, you can't move them out of the state," Misseri notes. "It's really complicated. It's one of those rescues that, if you don't have resources, you're really stuck."

Even horses were left behind, their owners unable to return to them when the waters rose. Some ended up standing in sewage-filled water for so long, their infected skin had peeled off.

"The waters may be receding, but that has brought a flood of animals who are in dire need," Blackwood explains. "Abandoned, starving, injured and ill. The reality is, time is running out and Guardians of Rescue is working to beat that clock."

But the flood of four-legged refugees continues to rage, even as more rescue groups pull out of the area. And not every cry for help can be heard. Sometimes, you have to peer over the fences.
